Green functions of currents in the odd-intrinsic parity sector of QCD

The independent operator basis of the most important resonances in the odd-intrinsic parity sector of QCD allows us to construct Lagrangians for corresponding Feynman diagrams of several types of interaction channels of the mesons and resonances. Here, we will discuss all three-point current correlators non-trivial for this sector. We briefly summarize their basic properties and high energy behaviour via the operator product expansion (OPE) framework. We also show that the vector field formalism is not compatible with the OPE, and for this reason the antisymmetric field formalism is a more suitable choice. We also briefly introduce some fundamental phenomological aspects that could be useful in the next studies
